[0002] During the forging process of automotive crankshaft connecting rod forged steel blanks, dimensional deviations such as thickness, flatness, and height differences often occur due to heat loss in the forging die or abnormalities in the production process. This can easily lead to final product defects. To ensure dimensional compliance, it is necessary to inspect the formed connecting rod blanks. Currently, the inspection of connecting rod blanks still relies on manual measurement or experience-based observation, which is extremely inefficient and prone to errors in judging compliance. Therefore, a rapid dimensional inspection device for connecting rod blanks is needed. Utility Model Content

[0020] To make this utility model clearer and more understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the given embodiments are only one of the implementation methods and do not represent all embodiments.

[0021] In this article, terms such as "inner," "outer," "upper," and "lower" are established based on the positional relationships shown in the attached drawings. Depending on the attached drawings, the corresponding positional relationships may also change. Therefore, they should not be interpreted as an absolute limitation on the scope of protection.

[0022] Combined with appendix Figure 1 -Appendix Figure 6 The system includes an inspection base 1, on which an inspection groove is formed. An inspection through-slot 16 is formed in the middle of the inspection groove. A first inspection block 2 and a second inspection block 10, with the same sliding direction, are slidably disposed within the inspection groove. Both the first inspection block 2 and the second inspection block 10 are connected to the inspection base 1 via a position adjustment mechanism. Each of the opposing ends of the first inspection block 2 and the second inspection block 10 has a standard part slot. When the opposing ends of the first inspection block 2 and the second inspection block 10 are aligned, the two standard part slots are joined to form a standard part groove 11. The standard part groove 11 corresponds in position to the inspection through-slot 16. The outline of the standard part groove 11 is the same as the outline of the standard part. Specifically, the width of the standard part groove 11 corresponds to the thickness of the standard part, and the width of the standard part groove 11 is the distance between the side walls of the standard part groove 11 at the first inspection block 2 and the side walls of the standard part groove 11 at the second inspection block 10. The length of the standard part groove 11 corresponds to the length of the standard part.

[0023] Specifically, a lower inspection base 5 is provided below the upper inspection base 1. One end of the top of the lower inspection base 5 is fixedly connected to one end of the bottom of the upper inspection base 1. The top surface of the lower inspection base 5 is an inclined surface, and the inspection groove is located above the inclined surface. The inclined surface of the lower inspection base 5 forms a slope, and the connecting rod blank passing through the standard part groove 11 and the inspection through groove 16 will fall onto the inclined surface of the lower inspection base 5 and slide down the inclined surface, which facilitates the collection of the connecting rod blank.

[0024] Specifically, the position adjustment mechanism includes two adjusting bolts 9, and through holes 17 are provided on both sides of the inspection base 1. The through holes 17 are connected to the inspection groove, and the length direction of the through holes 17 is consistent with the sliding direction of the first inspection block 2 and the second inspection block 10.

[0025] Two adjusting bolts 9 are slidably disposed in two through holes 17. One end of one adjusting bolt 9 extends into the inspection groove and is fixedly connected to the first inspection block 2, while the other end extends out of the inspection upper base 1. One end of the other adjusting bolt 9 extends into the inspection groove and is fixedly connected to the second inspection block 10, while the other end extends out of the inspection upper base 1. Both adjusting bolts 9 are threaded with an inner locking nut 6 and an outer locking nut 7. The inner locking nut 6 is located in the inspection groove, and the outer locking nut 7 is located outside the inspection upper base 1. By adjusting the distance between the first inspection block 2 and the second inspection block 10 through the adjusting mechanism, the width of the standard part groove 11 can be adjusted so that the width of the standard part groove 11 can correspond to the lower and upper limits of the standard part thickness, respectively. In the fixed state, the inner locking nut 6 and the outer locking nut 7 clamp the side wall of the upper inspection base 1, thereby fixing the adjusting bolt 9 and thus fixing the inspection block. When adjustment is required, tighten the inner locking nut 6 or the outer locking nut 7 so that the distance between the two nuts is greater than the thickness of the side wall of the upper inspection base 1, and loosen the upper inspection base 1. At this time, the adjusting bolt 9 can slide along the through hole 17, driving the inspection block to move, thereby adjusting the position of the inspection block. After the adjustment is completed, tighten the inner locking nut 6 and the outer locking nut 7 again so that the two nuts clamp the side wall of the upper inspection base 1.

[0026] Specifically, dovetail keys 4 are fixedly provided on the bottom surfaces of the inspection grooves on both sides of the inspection through groove 16. The length direction of the dovetail keys 4 is consistent with the sliding direction of the first inspection block 2 and the second inspection block 10. The bottom of the first inspection block 2 and the second inspection block 10 are each provided with a dovetail groove that matches the dovetail key 4. The first inspection block 2 and the second inspection block 10 are slidably connected to their respective dovetail keys 4 through the dovetail grooves. The two inspection blocks can slide along the dovetail keys 4. The dovetail keys 4 provide guidance and limit for the sliding of the inspection blocks, making the sliding of the inspection blocks more stable and less likely to detach from the dovetail keys 4. More specifically, the bottom of the first inspection block 2 and the second inspection block 10 can each be provided with two dovetail grooves. The bottom surface of the inspection groove is provided with dovetail keys 4 corresponding to the number of dovetail grooves. Providing two dovetail grooves for each inspection block can improve the stability of the sliding.

[0027] Specifically, the dovetail key 4 is fixedly connected to the inspection upper base 1 by a first fastening bolt 13. Specifically, the dovetail key 4 is provided with bolt through holes 17, and the inspection upper base 1 is also provided with bolt through holes 17 at the corresponding positions. The screw end of the first fastening bolt 13 passes through the two bolt through holes 17 from the dovetail key 4 and extends to the bottom of the inspection upper base 1. The portion of the first fastening bolt 13 located on the inspection upper base 1 is threadedly connected to a second fastening nut 14. By tightening the second fastening nut 14, the dovetail key 4 is fixed in the inspection groove.

[0028] Specifically, elongated grooves 15 are provided on the bottom surfaces of the inspection grooves on both sides of the inspection through groove 16. The length direction of the elongated grooves 15 is consistent with the sliding direction of the first inspection block 2 and the second inspection block 10. Bolt holes are provided on both the first inspection block 2 and the second inspection block 10. A second fastening bolt 3 is provided in the bolt hole. The screw end of the second fastening bolt 3 extends through the bolt hole and the elongated groove 15 to the bottom of the inspection upper base 1. The portion of the second fastening bolt 3 at the bottom of the inspection upper base 1 is threadedly connected to a first fastening nut 12. The first inspection block 2 and the second inspection block 10 can be further fixed by the cooperation of the second fastening bolt 3 and the first fastening nut 12. When it is necessary to adjust the position of the inspection block, the first fastening nut 12 is loosened, and the second fastening bolt 3 can move along the elongated groove 15 to follow its corresponding inspection block. After the position of the inspection block is determined, the first fastening nut 12 is tightened.

[0029] Specifically, the end of the adjusting bolt 9 located outside the inspection base 1 is fixed with an operating handle 8, which makes it convenient for the operator to pull the adjusting bolt 9.

[0030] Workflow: First, adjust the first inspection block 2 and the second inspection block 10 so that the width of the standard part slot 11 corresponds to the upper limit standard of the thickness of the connecting rod standard part. Place the connecting rod blanks one by one into the standard part slot 11. The connecting rod blanks that can pass through the standard part slot 11 are those with a thickness smaller than the standard thickness. Then, adjust the first inspection block 2 and the second inspection block 10 again so that the width of the standard part slot 11 corresponds to the lower limit standard of the thickness of the connecting rod standard part. Place the connecting rod blanks that did not pass through the standard part slot 11 in the previous test back into the standard part slot 11. The connecting rod blanks that can pass through the standard part slot 11 in this test are those with qualified thickness and flatness.

[0031] It is important to understand that the height difference to be tested is the thickness difference of the connecting rod blank, the thickness dimension corresponds to the height dimension, and the flatness refers to the flatness of the two sides formed by the width direction and the length direction of the connecting rod blank.
